How does fault current vary on the secondary of a power transformer (ie 115kv to 13.8kv 40MVA) as the tap changer adjusts up and down in relation to primary side voltage? Does the X/R ratio exhibit any change? Do I need a tester for exact values or can they be adjusted easily by hand in relation to those of the normal neutral position?
